4M KidzLabs Mega Hydraulic Arm

4M KidzLabs Mega Hydraulic Arm: Build It, Then Power It with Water

How does water make a robot arm move? Build the 4M KidzLabs Mega Hydraulic Arm and explore hydraulic power for yourself. Designed for ages 8+, this hands-on kit lets curious builders assemble a multi-axis robot arm, then use water to power its movement. Once built, it measures approximately 48 cm long and 28 cm tall.

What's Inside

The kit includes the components to assemble the arm, claw, base and hydraulic controls:

• 4 handles, 1 handle cover and 4 handle caps
• 1 left claw, 1 right claw, 2 claw connectors, 1 claw frame and claw pads
• 3 pegs and 2 stoppers
• 1 slider bottom, 1 slider top, 1 syringe cover, 1 syringe hinge and 1 syringe holder
• 6 needle caps, 7 plunger caps and 8 syringe barrels with plungers
• 1 base plate, 1 rotating frame, top arm frame and rotating base
• Long tube, 2 medium tubes and short tube
• 11 small screws, adhesive tab and 2 washer screws

Why Kids (and Parents) Love It

• Build first, experiment next: the finished model gives kids a way to explore the science behind their construction.
• Make hydraulic power tangible: water powers the arm, bringing an engineering concept off the page and into their hands.
• Enjoy a project with a purpose: assembling the frames, claw and controls is part of creating a working multi-axis robot arm.
• Keep the curiosity going: once the arm is assembled, try its controls and watch how the different parts move.

Good to Know Before You Buy

• Recommended for ages 8 and up.
• This is a build-it-yourself kit, not a ready-assembled robot arm.
• You will also need a small crosshead screwdriver, lubricant (lotion) and a used, cleaned tin can. These are not included.
• Water is required to power the hydraulic movement.
• The assembled arm is approximately 48 cm long and 28 cm tall, so allow room to build and use it.
